Do you mean that this is technically possible, or that this is a feature that will be supported? I've preordered the Time 2, so having the ability to configure it that way to significantly extend the battery life of the ring could be interesting. On the other hand, using it standalone might be fine for me. I wouldn't really know how fast I might go through the battery without using it for a while.

It says that lead fumes are unlikely to be generated:

Based on standard soldering iron temperatures of 620°F-700°F and the melting point of lead (621°F), it is unlikely that lead fume will be generated during electronic soldering, unless the solder is heated to lead’s vaporization temperature of 3182°F.

I think XY actually has better resolution depending on your perspective. I agree that the minimum extrusion is approximately a line width circle. But that circle can move less than the line width for features on larger surfaces. For example, if you emboss something on the side of an object with 0.3mm depth using a 0.4mm nozzle / line-width, it will work fine.

How is this Elon-hate? Is a founder someone who founded a company or someone who joined it later? Calling someone not a founder doesn't change their contributions to the company.

If it is happening all the time, providers of generative AI should be emphasizing a whole lot more that they can just make up information.

ChatGPT currently has this message in small text below the message prompt, but I'm not sure how long it has been there: "ChatGPT can make mistakes. Consider checking important information."

But I think that message is kind of underplaying it. The fact that it can make mistakes doesn't necessarily mean that the average person will think it is completely making something up.

And you downplay evidence of fraud. You mentioned studies where 1/3 to 1/2 of reviewed papers are found to not be replicable and say they get similar but weaker results. This is evidence of p-hacking or data manipulation. You should expect far less papers to not be replicable given proper statistics.

Without watching the video referenced in the article, I'm guessing this was based on what they theoretically could do, rather than something that they had actually implemented.

They currently only use the load cells for bed leveling: https://www.youtube.com/watch?v=F7ETSVu04ao&t=940s

I could be wrong, but I would expect that the load cell readings would be far too noisy in order to determine the height of the nozzle while printing. Even if they were accurate, different materials would also behave differently due to different viscosities.

I'm not aware of any hotend sensors doing as you describe. The Prusa MK4 only uses it to generate a bed mesh the same as any other bed-leveling sensors. It does not do any live calibration while printing.

They measure a series of points to get a bed mesh, the same as other leveling sensors do. You shouldn't need to live-adjust z, because you've measured the bed surface with the nozzle tip.

With a BLTouch, you need to adjust the z-offset, because the nozzle tip and the BLTouch trigger height are not the same. Once that is calibrated, it should continue to work fine as long as the sensor is working properly.

I think it mainly comes down to the accuracy of the sensor. If your sensor gives you a +-0.03mm reading when probing the same spot, then you will have high and low spots in your bed mesh that you can't correct with z-offset.

This could explain your issues with the BLTouch you mentioned in another thread here. I have various brands of knockoff BLTouch sensors, and the worst one had a +-0.02mm range when measuring points, which made it impossible to get a good bed mesh. The one I replaced it with had about a +-0.005mm accuracy, which fixed my issues with the low and high spots.

If they're using pirated books, haven't they already committed copyright infringement by keeping these copies? The model itself might be transformative, but I think that is a separate issue.

If the companies had bought all of the ebooks, then they might be in the clear.

I don't think it is sustainable for Twitter to hand out ad revenue site-wide at this point. All they have done so far is to pay out to a small group of people. Musk has said that ad revenue is down 50% and that they are not currently profitable.

It never was alive. A fork where the only development is renaming everything to crablang is pointless.

I'm not the parent commenter, but the friction point for me is the slowness when typing the first few characters in an interactive search (I have a large history). I think the searches are synchronous with each keystroke, right? It would feel a lot faster if each keystroke could cancel an in progress search instead of waiting for it to finish.

In fzf, there is no noticeable lag when typing.
